The National Agricultural Research Organization (NARO) has ruled out poisoning as one of the causes of mysterious death of fish on Lakes Victoria and Kyoga.

NARO said upon interactions with the fishing communities at different landing sites, it realized this has been a common phenomenon called Kaliro (hypoxia) that leads to fish death (kutumbuka).

The organization however added that the fishermen are concerned that the death rate was much higher than before as old and young nile perch fish were affected.

According to NARO, Samples (including the dead fish and water samples) were picked from the above mentioned landing Sites and these were taken for further analysis.

NO POISONING OF FISH ON L. VICTORIA AND L. KYOGA –
PRELIMINARY FINDINGS
Introduction:

Following increased media reports about dead fish floating on water and being swept ashore on parts of Lake Victoria, Lake Kyoga and River Nile, a team constituting of Senior Fisheries Inspectors, Senior Laboratory Officer and Laboratory Officers was dispatched by the Directorate of Fisheries Resources on 5th January 2021 and yesterday 9th January, 2021 Researchers from NARO’s National Fisheries Resources Research Institute on a fact finding mission that included sample collection from various landing sites in Wakiso district.

The sites were: Kasenyi landing
site and surrounding areas, Gguda landing site (greenfields), Bugonga landing site and Kigungu Landing site and Wagagi Flower Farm and Lido beach.

From the interactions with the fishermen
at the landing sites, many said that this is a usual phenomenon called Kaliro (hypoxia) that leads to fish death (kutumbuka), this time however, the fishermen said that the death rate was much higher than before as old and young nile perch fish were affected.

Water and fish Samples Picked:
Samples (including the dead fish and water samples) were picked from the above mentioned landing Sites and these were taken for further analysis.

These samples have been taken for analysis at THREE labs as shown below:
(1) Directorate of Government Analytical laboratory (DGAL) – (for toxicology)
(2) National Fisheries Resources Research Institute Laboratory – (for Algae analysis)
(3) National Animal Disease diagnostics and Epidemiology Centre (NADDEC) – (for
Pesticide Residue Analysis)

Note: Water samples similar to those taken to NADDEC lab were also taken to Ministry of Water and Environment Laboratory for comparative and confirmatory analysis.

Preliminary Conclusions:
As we await the comprehensive laboratory findings report due on Monday January 11th, 2020, preliminary investigations have ruled out fish poisoning.
